BMW E90 auto parts

The BMW E90 3 Series (2005-2013) includes various models such as 316i, 318i, 320i, 323i, 325i, 330i, 335i, and the high-performance M3 (E90 M3). Each model has unique characteristics in terms of engine, suspension, braking system, and exhaust setup. Below is a detailed comparison of auto parts across different models:

1. 316i / 318i / 320i (Entry-Level Models)

• Engine: Equipped with N43/N46 naturally aspirated inline-four engines (1.6L and 2.0L), offering decent fuel efficiency but moderate power.
• Transmission: 6-speed manual or 6-speed automatic (Steptronic).
• Suspension: Standard comfort suspension, with optional M Sport suspension.
• Braking System: Standard-sized brake discs, suitable for daily driving.
• Exhaust System: Single-sided, single-exit exhaust, quieter than higher trims.

2. 323i / 325i / 330i (Mid-to-High-End Naturally Aspirated Models)

• Engine: N52/N53 naturally aspirated inline-six engines (2.5L to 3.0L), providing more power and smoother operation.
• Transmission: 6-speed manual or 6-speed automatic (some later models feature an 8-speed auto).
• Suspension: More performance-oriented than entry-level models; some versions come with M Sport suspension as standard.
• Braking System: Larger brake discs for improved stopping power.
• Exhaust System: Dual-sided, single-exit exhaust with a sportier tone.

3. 335i (High-Performance Turbocharged Model)

• Engine: N54 (twin-turbo) or N55 (single twin-scroll turbo) 3.0L inline-six engine, delivering significantly higher power.
• Transmission: 6-speed manual or 6-speed automatic (7-speed DCT optional on later models).
• Suspension: More aggressive M Sport suspension for better handling and cornering stability.
• Braking System: Larger brake rotors and calipers, superior to naturally aspirated models.
• Exhaust System: Dual-sided, dual-exit exhaust, producing a deeper, more aggressive sound.

4. E90 M3 (High-Performance M Power Model)

• Engine: S65 4.0L naturally aspirated V8, high-revving with exceptional power output.
• Transmission: 6-speed manual or 7-speed M-DCT dual-clutch transmission for faster gear shifts.
• Suspension: M-specific suspension tuning, aluminum front and rear subframes for enhanced handling.
• Braking System: Larger M-performance brake system, optimized for track use.
• Exhaust System: M-tuned sports exhaust with an aggressive, high-pitched sound.
• Chassis Materials: Lightweight components, including carbon fiber and aluminum, reducing weight for better performance.

Each model shares a modular design, allowing some parts to be interchangeable. However, performance-oriented models (335i and M3) feature upgraded parts for enhanced power and handling, requiring higher maintenance costs. If you need recommendations on specific parts, let me know!
